PTZ Method and apparatus for video surveillance by using pan-tilt-zoom camera

摘要

Active video surveillance network that can actively monitor video by providing orientation and viewing angle information for shooting area using PTZ camera with built-in geomagnetic sensor and linking PTZ camera with geodetic sensor to GIS map do. It is possible to implement a thorough surveillance system by rapidly propagating the alarm situation due to the event detected by a specific PTZ camera to a plurality of PTZ cameras included in the video surveillance network and switching the surveillance direction of each PTZ camera to the area requiring centralized surveillance have.
